In the diagram, WZ=StartRoot 26 EndRoot.

gogolik [260]

Answer:

$P = 8 + 2\sqrt{26}$

Step-by-step explanation:

Given

$W = (-2, 4)$

$X = (2, 4)$

$Y = (1, -1)$

$Z = (-3,-1)$

Required

The perimeter

First, calculate the distance between each point using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 -y_2)^2$

So, we have:

$WX = \sqrt{(-2- 2)^2 + (4-4)^2 } =4$

$XY = \sqrt{(2- 1)^2 + (4--1)^2 } =\sqrt{26}$

$YZ = \sqrt{(1- -3)^2 + (-1--1)^2 } =4$

$ZW = \sqrt{(-3--2)^2 + (-1-4)^2 } =\sqrt{26}$

So, the perimeter (P) is:

$P = 4 + \sqrt{26} + 4 + \sqrt{26}$

$P = 8 + 2\sqrt{26}$

11y^2-19y-10=-4y^2 <br> all real solutions

tangare [24]

Answer:

y=5/3 is the only real solution

Step-by-step explanation:

Solve for y over the real numbers:

11 y^2 - 19 y - 10 = -4 y^2

Add 4 y^2 to both sides:

15 y^2 - 19 y - 10 = 0

The left hand side factors into a product with two terms:

(3 y - 5) (5 y + 2) = 0

Split into two equations:

3 y - 5 = 0 or 5 y + 2 = 0

Add 5 to both sides:

3 y = 5 or 5 y + 2 = 0

Divide both sides by 3:

y = 5/3 or 5 y + 2 = 0

Subtract 2 from both sides:

y = 5/3 or 5 y = -2

Divide both sides by 5:

Answer: |

| y = 5/3 or y = -2/5
